Firearm Bolt Emulation Mechanism

ABSTRACT

A firearm bolt emulation mechanism includes a bolt body. The bolt body includes a hand grip movably mounted thereon and having a function of reciprocal movement. The hand grip has an end coupled to a gas tube over which an elastic element is fit. The gas tube is coupled to a striker that is received in the bolt body. A knocker is received in the bolt body and is set on a reciprocal movement path of the striker. As such, for percussion, the hand grip is moved rearward to emulate a chambering operation and at the same time, the hand grip drives the gas tube and the gas tube drives the striker to move simultaneously. When the hand grip returns to the original position, the striker powerfully strikes the knocker so as to generate loud and clear sounding similar to the chambering sound of an actual firearm.

(a) TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to firearm bolts, and more particularly to a firearm bolt emulation mechanism that generates a highly emulating chambering sound to effectively enhance the pleasure of a player.

(b) DESCRIPTION OF THE PRIOR ART

In the 16th century, artillery was reduced in size and matchlocks were invented as the beginning of the light firearms. Since then, firearms gradually become extremely offensive weapons with the combination of innovation of mechanical engineering and novel types of gunpowder. The development of industrial techniques also helped advance the progress of firearms, making them widely used in military and police applications, hunting, and sports.

Firearms are restrained and controlled in many countries and firearm fancies are only allowed to purchase toy gun or model guns for collection and possession. A variety of emulation firearm bolts that does not possess antipersonnel force are available in the market and some are referred to as toy gun bolts or BB guns.

The toy gun bolts that are currently available in the market have made a great progress in respect of the materials and the manufacturing techniques thereof, making the outside appearance of the toy gun bolt highly closely emulating an actual firearm. However, the internal structure of the toy gun bolt is generally not made emulating an actual bolt. For example, the operation of the toy gun bolt does not provide a power vibration and chambering sound that an actual gun may generate, making the operation of the toy gun bolt very monotonous and boring. Toy gun bolts that generate recoil forces are also available in the market. Although a recoil force is generated in pretty much the same way as an actual firearm, the sound generated when chambering is made is still poor. Electronic sound generation has also been available for such a purposes, but there is a significant difference from the chambering sound of an actual firearm.

SUMMARY OF THE INVENTION

The primary object of the present invention is that through connection made with a gas tube, when a hand grip is pulled and moved, the gas tube drives a striker to move so as to realize a structure for emulation of an actual bolt in a limited space.

Another object of the present invention is that striking and contacting between a striker and a knocker may generate sounding that is very close to actual chambering sounds so as to achieve an advantage of high degree of emulation thereby enhancing the pleasure of a user in the use of the device.

To achieve the above objects, the present invention structurally comprises a bolt body, a gas tube received in the bolt body and coupled a the hand grip, a striker received in the bolt body and coupled to an end of the gas tube, a knocker received in the bolt body and set on a moving path of the striker, and an abutting member fixedly mounted to one side of the striker to enhance tight engagement thereof with the knocker. The gas tube comprises an elastic element fit thereon for reciprocal movement of the hand grip. Further, the striker has one side forming a wavy section and the knocker has a side corresponding to the wavy section and forming a contact section. As such, for percussion, the hand grip is first pulled rearward for chambering and at the same time, the hand grip drives the gas tube to have the gas tube drive the striker. Further, the hand grip is returnable by means of a force applied by the elastic element in an opposite direction. During the process of position returning, the striker powerfully strikes the knocker, making the wavy section and the contact section rub each other so that they generate loud and clear sounding in an intermittent manner, achieving the sound of chambering of an actual firearm and thus improving the pleasure of a player.

The technique described above can overcome the problems of the conventional toy gun bolt that generates no chambering sound as an actual firearm and is thus monotonous and boring and lacks of the true sense of reality, thereby achieving a practical improvement of the present invention.

The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

Referring to FIGS. 1, 2, and 3, the present invention comprises:

a bolt body 1, which comprises a movably arranged hand grip 11, the hand grip 11 having an end to which an elastic element 12, which can be a spring, is mounted for reciprocal movement of the hand grip 11 and an opposite end fixedly coupled to a connection member 13, the connection member 13 having an end fixedly coupled to a striker 14 to be described hereinafter;

a striker 14 (which is a solid metal piece), which is received in the bolt body 1 and coupled to the connection member 13 of the hand grip 1, the striker 14 having a side forming a wavy section 141;

a knocker 15 (which is a solid metal piece), which is received in the bolt body 1 at a location adjacent to a front end of a barrel and is set on a moving path of the striker 14, the knocker 15 having a side corresponding to the wavy section 141 and forming a contact section 151; and

an abutting member 16, which is fixedly mounted to one side of the striker 14 to enhance tight engagement thereof with the knocker 15, the abutting member 16 being arranged to be distant from the wavy section 141.

Referring go FIGS. 2 to 5, when a chambering operation is carried out, a loud and clear sound is generated, similar to the chambering sound of an actual firearm. Firstly, a user holds the bolt body 1 with a hand and pulls the hand grip 11 rearward, whereby at the same time, the elastic element 12 is compressed by the hand grip 11 and undergoes deformation. Further, the hand grip 11 drives, via the coupling of the connection member 13, the striker 14 to move so as to cause the striker 14 to displace with respect to and rub against the knocker 15 thereby generating intermittent sounding due to the configurations or shapes of the wavy section 141 and the contact section 151, until the hand grip 11 reaches a predetermined position. Further, the elastic element 12 that is compressed selectively initiate position returning and applying a push force to the hand grip 11 for movement in a direction toward the front end of the barrel, whereby the hand grip 11, when released by the user, is driven by the elastic element 12 to make the striker 14 powerful strike the knocker 15. Thus, similarly, through the cooperative operation between the wavy section 141 and the contact section 151, loud and clear sounding may be generated in an intermittent manner. Further, the striker 14 and the knocker 15 are solid metal pieces and thus, the striking sound generated thereby is close to the chambering sound of an actual firearm. Further, to improve the tight contact force between the striker 14 and the knocker 15, the abutting member 16 is provided to bias and cause the striker 14 to abut against the knocker 15, preventing any separation occurring therebetween.

Referring to FIGS. 6, 7, and 8, in another embodiment, the present invention comprises:

a bolt body 1 a, which comprises a movably arranged hand grip 11 a, the hand grip 11 a having an end to which an elastic element 12 a is mounted for reciprocal movement of the hand grip 11 a;

a striker 14 a, which is received in the bolt body 1 a and coupled to the hand grip 11 a, the striker 14 a having a side forming a wavy section 141 a;

a knocker 15 a, which is received in the bolt body 1 a and is set on a moving path of the striker 14 a, the knocker 15 a having a side corresponding to the wavy section 141 a and forming a contact section 151 a; and

an abutting member 16 a, which is fixedly mounted to one side of the knocker 15 a to enhance tight engagement thereof with the striker 14 a, the abutting member 16 a being arranged to be distant from the contact section 151 a.

Referring to FIGS. 7-10, when a user pulls and moves the hand grip 11 a, the wavy section 141 a of the striker 14 a and the contact section 151 a of the knocker 15 a rub each other and generate loud and clear sounding in an intermittent. On the other hand, when they are driven to move in an opposite direction by a returning force of the elastic element 12 a, similar sounding may also be generated. Further, the abutting member 16 a is provided to set the knocker 15 a in a more tight engagement with the striker 14 a to ensure bettered engagement.

Referring to FIGS. 11, 12, and 13, in a further embodiment, the present invention comprises:

a bolt body 1 b, which comprises a movably arranged hand grip 11 b, the hand grip 11 b having an end to which a gas tube 17 b is coupled, the gas tube 17 b receiving an elastic element 12 b to fit thereon in an encompassing manner;

a striker 14 b, which is received in the bolt body 1 b and coupled to an end of the gas tube 17 b, the striker 14 b having a side forming a wavy section 141 b, the striker 14 b being connected to an end of the elastic element 12 b that is distant from the hand grip 11 b; and

a knocker 15 b, which is received in the bolt body 1 b and is set on a moving path of the striker 14 b, the knocker 15 b having a side corresponding to the wavy section 141 b and forming a contact section 151 b.

Referring to FIGS. 12-15, when a user pulls and moves the hand grip 11 b, the hand grip 11 b drives, via the coupling of the gas tube 17 b, the striker 14 b to move rearward. At this time, due to the biasing of the elastic element 12 b, the striker 14 b is provided with a capability of position returning. Thus, in position returning, the striker 14 b and the knocker 15 b engage and rub each other so that the wavy section 141 b and the contact section 151 b may generate loud and clear sounding in an intermittent manner. The instant embodiment features the gas tube 17 b driving the striker 14 b to generate reciprocally repeated striking thereby effectively providing a striking structure inside an existing bolt body 1 b without any modification of the outside configuration.

The present invention provides the following advantages:

(1) Through the connection made with the gas tube 17 b, when the hand grip 11 b is pulled and moved, the gas tube 17 b drives the striker 14 b to move so as to realize a structure for emulation of an actual bolt in a limited space.

(2) The striking and contacting between the striker 14 and the knocker 15 may generate sounding that is very close to actual chambering sounds, achieving an advantage of high degree of emulation thereby enhancing the pleasure of a user in the use of the device.

It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
